How a Realist Hero Rebuilt the Kingdom: Volume 7

Having returned from the Star Dragon Mountain Range, Souma heads to the next destination on his diplomatic tour, the Republic of Turgis. While he is there to investigate the possibility of forming cordial relations with a neighbor they currently have no interaction with, Souma finds his attention drawn to the high level of the local blacksmiths, and a plan occurs to him.
Sensing that state level negotiations will be necessary to make his plan a reality, he succeeds in arranging a meeting with the republic's head of state. In order to make the negotiations fruitful, Souma demonstrates the kingdom's power to the republic.
“I will show the republic the 'gain' to be had from working with us, and the 'threat' to make them hesitate to oppose us.”
Can Souma's secret plan move the republic?!
